The new reprocessing plants UP3 and UP2-800 in France and Rokkasho in Japan use or will use an improved technology for their extraction cycles. The equipment selected are pulse columns (cylindrical and annular) and mixer-settlers (normal type and extra-flat type). This paper presents the equipment selected for each plant and the extensive R and D performed especially for pulsed columns by CEA and also the results of first active runs in UP3.
